    88-98 OBS turbo hotside parts

    Throwing this out there for guys with OBS trucks with GenIII motor conversions… I’m going back to NA for now and am working on another project that I could use some $$$ for.

    Wanting to sell my turbo setup minus the turbo and intercooler so including the hotside piping (minus exhaust manifolds), coldside piping (including couplers and t-bolt clamps), downpipe, bov and wastegate. Hotside piping is 304 stainless steel schedule 10 piping and; has two flex couplers to allow for thermal expansion. Downpipe is 3.5” diameter 304 stainless. Wastegate is a Tial 46mm unit with 4 bolt flanges. Turbo flange is t4 with a 3” outlet I believe so any small frame t4 should bolt in. Inner fender required a little massaging after a few heat cycles but nothing too drastic. Cold side piping is 3” diameter mild steel (has some surface rust but nothing that a wire brush wouldn't take care of) and the bov is a 50mm tial unit.

    Asking $1099 for the setup including shipping and insurance to the lower 48 states.

    For those interested in just the hotside/downpipe setup I'm asking $699 for the setup with wastegate or $299 without

    Just pick up a master power or magnum turbo for 500-600 and a cheap ebay intercooler and you have a turbo setup for your OBS truck for less than 2K.

    I've seen a few master power units for sale for 450-600 depending on the size (t70 or t76) and if they're used or not.
